To all whom it may concern:

Be it known that T, J OKICHI TAKAMINE, Jr.,'a subject of the Emperor ofJapan, residing at New ,York, county and State of New York, have made acertain new and useful Invention in Ice or Water Bags, of which thefollowing isa specification.

The invention relates to ice or water bags.

The object of the invention is to provide an ice or hot water bag, whichis simple in structure and which, when applied to the portion of anatomywhere hot-or cold packs are required, will confine the heat or thecoldness, as the'case may be, to that particular portion. 1 A.

A further object of the invention is to provide a bag of the classdescribed which will prevent the heat or coldness contained therein fromdiminishing due to radiation or other causes.

Further objects of the invention will appear more fully hereinafter.

The invention consists substantiallyin the construction, combination,location and relative arrangement of parts, all as will be more fullyhereinafter set forth, as shown in the accompanying drawing, and finallypointed out in the appended claims.

Referring to the drawings;

Figure 1 is a top plan view of a bag embodying my invention.

Fig. 2 is a view in elevation and in section taken on the line 2-2 Fig.1, and looking in the direction of the arrows.

Fig. 3 is a top plan view of a modified construction embodying myinvention.

Fig. 4 is a view in elevation and in section taken on'the line 4, 4,Fig. 3, and lookin%in the direction of the arrows.

ig. 5 is a bottom plan view of one end of the bag, shown in Figs. 3 and4.

The same part is designated by the same reference numeral wherever itoccurs throughout the several views.

In the ordinary hot or cold water bags,

or ice bags, nowused for sick room purposes, one greatobjection is thatwhether the bags are constructed of metal or rubber the heat or thecoldness, as the case may be, quickly loses its degree'of ,eflectivetemperature, due to radiation. -Where hot ap lications are desired, onlyone portion o the bag comes in contactwith the portion of the anatomy towhich the bag is a plied and consequently the remaining sur ace 0 y thebag is free to radiate the heat there Specification of Letters Patent.

from, with the consequence that the water in the bag quickly loses itsefiective temperature, thereby necessitating frequent renewal of the hotwater, and sub ecting the portion of the anatomy ofthe patient to frequent applications of varyingtemperatures, when the best results areobtained with continuous application of the 1 same temperature. The sameis true with respect to the ice bag. The ice quickly melts, due to theSurface of the bag beingin constant communication with the air of theroom. 7

In accordance with my invention, T obviate these and many otherdifliculties, by employing a; thermally sealed. vessel of roundedcontour, and with a flat bottom portion, preferably of rubber or otherheat or cold conducting material.

In th drawing, 1 designates the outer and 2, t e inner walls of thevacuum space, 3, which walls are constructed of any suitable materialand sealed air tight in any well known manner. Suitably secured to thewall 1 of the bag is a flat base or bottom portion 4:. This bottomportion may be of any suitable material, such as metal, rubber, or anytemperature conducting material. T find it preferable to employ rubberfor this purpose, as it admits a degree of elasticity of the contactsurface of the bag which enables the ready adaptability of the bag topractically any portion of the human anatomy, but my invention in itsbroad sco e is not to be limited in this res ect.

he thermally sealed rounded wal of the bag is provided with an opening,and neck portion preferably in the center thereof, as indicated at 5,over which may be secured or otherwise fastened, a cap or cover 6.

Thus it will be seen that when the bag is to be employed, say for hotapplications, hot water is admitted therein through the neck or opening5, and the cap 6 is screwed thereto. The ag is then applied to the placewhere hot application is desired. The

of time. It will be understood that the same principle is involved wherecold'applicatlons are required, and ice or cold water is supplied to thechamber 8 of the bag instead of the hot water.

If desired, buckle straps 9 and 10 may be provided, attached to the bagon opposite sides thereof, to allow the bag to be fastened to the bodyof the user, thereby preventing displacement by the movement of theuser.

In the form of my invention shown in Figs-3, 4, and 5, I eliminate theneck por tion 5, and the cap or cover 6, and employ for the base orbottom portion some such material as rubber, water proof canvas, orother material, or combination of the same. In this form, the base 4, isfastened to the bottom ofthe curved vacuum wall -1 up to the pointthereon indicated at 12. From this point the bottom portion 4, extendsin the shape of a converging flap as indicated at 13. It will be seenthat by this structure, an opening 14 is provided to the chamber 8,through which the hot water or ice, as the case may be, is admitted tothe ba Whenthe bag is fitted for use, the flap 13, 1s

pulled taut around the upper outer surface of the bag and securedthereto in any suitable manner. I show one simple arrangement for thispurpose, wherein the end of the flap 13 is provided with a male clip 15,Wl'llCh fastens into a female clip 16, on the surface of the bag, asshown. Where rubber or other elastic material is employed for the flap13, a number of female clips 16, may be employed, as shown, to allow anydegree of tautness desired or required to make the bag watertight.

While I have shown and described several specific arrangements embodyingmy invention, it will be understood that many difl'erent forms willreadily suggest themselves to those skilled in the art without departingfrom the broad scope of my invention as defined in the claims.

Therefore, what I claim as new and useful and of my own invention, anddesire to secure by Letters Patent, is,-

1. A bag for hot or cold applications comprising a concave side providedwith heat insulating means, and a flexible heat conducting side.

2. A bag for hot or cold applications comprising a concave thermallysealed side, an elastic heat conducting side, and means for introducingmaterial through the thermally sealed side. I

3. A bag for hot or cold applications comprising a cup-shaped sidecomposed of double walls confining heat insulating material and aflexible heat conducting side, whereby to prevent radiation from oneside of the bag and to locally apply the heat conducting sides toconform to an irregular body, substantially as described.

In testimony whereof I have hereunto set my hand this 10th day ofFebruary,

JOKICHLTAKALHNE, JR.
